darkly

Synonym discussion
Sense: adverb/1
All four words describe something frightening or hostile, but they differ in what they emphasise. 'Menacingly' focuses on a direct physical threat — someone leaning forward with a weapon or a growling dog. 'Ominously' points toward a future bad event without the threat being personal or immediate; a dark cloud gathering ominously does not threaten you directly. 'Sinisterly' suggests hidden, twisted evil — often supernatural or morally corrupt, like a villain's lair described as sinisterly quiet. 'Darkly' overlaps with all three but is the broadest: it can describe a threatening tone of voice ('he said darkly'), a gaze, or an atmosphere. It is more about the emotional colour of the moment than about predicting danger or showing evil. For example: 'The butler smiled darkly as he locked the door' suggests a cold, unsettling amusement — not quite menacing, not quite sinister, but carrying a threat in its mood.

Etymology
Darkly comes from Old English deorc, meaning 'without light' or 'gloomy'. The suffix -ly, which turns adjectives into adverbs, was added in Middle English. The original sense was simply 'in a dark manner (with little light)'. The threatening meaning developed later through metaphor: darkness became linked to evil, danger, and secrecy, so doing something 'darkly' took on the sense of acting with hostility or sinister intent. By the 1500s, English writers were using darkly to describe both physical dimness and emotional gloom.
